SLAC Parallel Electromagnetic Code Development &
Applications*

The suite of parallel electromagnetic codes under development at SLAC now
consists of the eigensolver Omega3P, the time-domain solver Tau3P, and the statics
solver Phi3P. These codes are based on conformal meshes to preserve the geometry
fidelity of complex three-dimensional structures, and are designed for parallel
computing on architectures that will soon reach the terascale regime. Such a
simulation capability already enables accelerator structure modeling that requires
mesh resolution close to the fabrication tolerance. Terascale computing resources
will further allow simulations of multi-components on a system level previously not
deemed possible. This poster will review the status of the codes and will report on
the accelerator design problems that have benefited from their use.
